Speaking at the Tesla 'All Hands' event, Elon Musk talked a lot about its humanoid robot Optimus. Elon said "Optimus will be the biggest product of all time by far. Nothing will even be close. I think it'll be ten times bigger than the next biggest product ever made." Robotics really has been one of the major stories of 2025 so far, and with Tesla looking to produce 5,000 Optimus bots this year alone, it's only going to get bigger.

Perplexity CEO Aravind Srinivas announced that starting next week, their new agentic browser Comet will begin public testing with a small set of users. He also hinted that this intriguing new product might only be weeks from a full release. What exactly we will be getting from Comet remains to be seen, but we're likely to get quite a few hints next week.

Grok now has a dedicated image editing mode. It had already been possible to instruct Grok to make some edits to an image, but now it's properly built into the interface. Simply click on the edit image button, upload an image, and tell Grok what you want to change. Finally, not content with performing the world's first robotic side flip, the unitary G1 decided to do a kip up, which in some ways seemed even more impressive.

But it didn't stop there. The G1 went on to do some advanced combat moves and then showed some incredible stability and self correction after being unceremoniously kicked. Please don't kick the robots.
